Cashback terms and exclusions

What will stop me getting my cashback?
  • Using a discount code or voucher code not posted and approved by TopCashback.
  • Purchase of gift cards or use of gift cards for full or partial payment will result in your cashback being ineligible.
  • Existing Customers are ineligible for cashback.
  • Tablet + Data SIMs are ineligible for cashback.
  • If you return or cancel your order then you will no longer be eligible for cashback and you will see the cashback move to Declined in your account.
What else is essential?
